Abstract

PURPOSE:To perform perfect difference control between motors by giving the value of plural reference pulse trains counted by common sampling time as digital speed reference for each motor. CONSTITUTION:Each pulse oscillator 2 generates the pulse trains RP of the frequency which are proportional to a target speed. A speed setting circuit 1 outputs the digital speed reference DD. The digital speed reference DD is displayed on a digital speed indicator 30 and also inputted to a speed control arithmetic section 2 by the computer in the control section of each motor. The pulse train speed reference RP and a pulse feed back signal FP from a pulse oscillator 7 are inputted to a PLL control circuit 11. The PLL control circuit 11 outputs an analog signal Y which is proportional to the phase difference between the pulse train speed reference RP and the feed back pulse FP. The pulse phase difference signal Y is added to the analog current reference in a current control section 3.
